Gahow Wang 6b24bedcbd research: daytime reversal of the overnight gap on S&P 500 (STOP) ...

Buying the biggest overnight losers at 09:35 and selling at the close earns
1-6 bp a day gross on 2016-26 Alpaca 5-min bars; net Sharpe ~0, and stacking
it on the overnight sleeve lowers the Sharpe (1.27 -> ~0.8).
